Do you want to create your own wiki? There are quite a few web applications that can help. Some require you to pay for this service, while others allow you to do so for free.

1. MediaWiki
MediaWiki is one of the most popular wiki platforms on the web. It is completely open and allows you to create a free knowledge base.
Originally used on Wikipedia, the site now offers a backend for many other common wikis, including Wiktionary, Wikimedia Commons, and Wikidata.
The biggest advantage of the platform is its impressive customization capabilities. There are more than 1,900 extensions, 900 configuration settings, and support for 300 languages.
To use MediaWiki, you need a server running PHP and a compatible SQL database.
2. SlimWiki
Many people don't have the time or technical knowledge to use popular wiki platforms like MediaWiki. If you're looking for an easier way to create a wiki, take a look at SlimWiki. It's free for most three users, and each requires a $5/month response.

3. Wikidot
If you want to create your own wiki but don't know HTML, PHP, JavaScript, etc., then Wikidot is another site worth checking out. Since its launch in 2006, it has become one of the largest wikis in the world. The free version supports five users. Each user gets 300 MB of disk space. For $49.90 per month, the storage limit is increased to 30 GB and the number of users is increased to 10. The most expensive plan costs $239.90 per month. It offers unlimited users and 200 GB of storage.

4. Tiki Wiki
Tiki Wiki is an Open Source content management system, just like MediaWiki.
Here you can use the WYSIWYG editor, complete revision history storage, revision comparison tools, and RSS wiki protocols. The Tiki Wiki also has an impressive library of plugins.

5. DokuWiki
At first glance, DokuWiki is very similar to MediaWiki and Tiki Wiki. However, it boasts a much easier learning experience and is free of charge.

6. Fandom
Fandom (known as Wikia until early 2019) is another easy-to-use wiki site for those who want to create a free knowledge base.
Wiki projects are based on the internal MediaWiki interface. This allows users to take advantage of many of the platform’s benefits without having to worry about hosting and other technical issues.
